Drive Unit Installation
The drive unit (sold separately) must be connected to your
rudder control so the GHP Reactor Mechanical autopilot can
steer your boat. When you purchase a drive unit sold by Garmin,
it will include the correct cables, connectors, and instructions.
If a drive unit is installed on your boat already, you can use a
drive unit power cable (sold separately) to adapt your drive unit
for use with the autopilot system.
If you connect the autopilot system to a drive unit not sold by
Garmin, you must also provide rudder-feedback information by
installing and connecting a Garmin rudder-feedback sensor
(recommended) or by connecting to an existing rudder-feedback
sensor on your boat using a rudder feedback cable (sold
separately).
Installing a Garmin Drive Unit
Follow the installation instructions provided with your Garmin
drive unit to mount it and connect it to your rudder control and
autopilot system.
Corrosion Blocker
NOTICE
To ensure long life of all parts, apply corrosion blocker to the
drive unit at least twice yearly.
A marine-rated corrosion blocker should be applied to the drive
unit after all connections are made.
Connecting to an Existing Drive Unit
You must install a drive unit power cable to use a drive unit not
sold by Garmin with the GHP Reactor Mechanical autopilot. This
cable is sold separately.
These instructions do not apply to a solenoid-type drive unit
(
